WILLIAM H. GARDNR, OF BASIC CITY, VIRGINIA, ASSIGNOR TO WILLIAMS PATENT CRUSHER & PULVERIZER COMPANY, OF ST.- LOUIS, MISSOURI,

A CORPORATION OF MISSOURI.

CRUSHER AN D PULVERIZEH.

Patented Feb. 2e, 1967.

To all whom it may concern:

Be it known that I, WILLIAM H. GARD- NER, a citizen of the United States, residing at Basic City, Virg.nia, have invented a certain new and useful Improvement in Crushers and Pulverizers, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertainsl to make and use the same, reference being had to the accompanying drawings, forming part of this speciication.

:Figure 1 is a' vertical longitudinal sectional view through the casing oi' a Crusher and pulverizer, the disintegrating mechanism being shown in elevation; and Fig. 2 is a 'perspective view of a number of the hammersupports and hammers carried thereby.

'1 his invention relates to the eneral class of Crushers and pulverizers; an one of the objects thereof is to provide a disintegrating mechanism, including 'a shaft with radial hammers arranged thereabout and swingingly secured in their relative positions, so that the centrifugal action of the shaft will cause the hammers to contact with the materi al to be acted upon and to provide means for preventing interierence between the respective hammers.

In the drawings I have illustrated a casing which I' designate by the reference-numeral 1 and having a cage or grate 2 at the bottom portion thereof; but this casing and cage may e of any other'preferred form adapted for v the purpose to be accomplished.

In the casing is mounted a shaft 3, on which are a plurality of substantiall triangularhammer-supports 4, having ra ial wings, (designated by the reference-numerals 5, 6, and 7, respectively.) These hammer-supports are arranged side by side on the shazt 3, to which they are pre erably keyed by a key 8, insertible in a keyway 9 in the respective hammer-supports and in a similar keyway in the shaft. The hammer-supports are arranged in alternating seriesthat is tosay, the projecting wings on one hammer-support are arranged intermediate the correspending wings on the adjacent supportso t at the hammers 10 may be pivoted and disposed radially around the shaft. The hammers 10 are illustrated as being of the hawkbill type; but other forms may be employed, if desired. The pivots 11 extend through openings 12 in the respective Wings, and these pivots preferably consist of rods which project through the entire series of supports; but separate pivots might be employed in lieu or the rods 11. Stops (illustrated as rods 13) pass through openings 14 in the respective wings, and these stops 13 are arranged adjacent to lthe pivots of the respective hammers and are supported by the same wing which carries the particular hammer whose movement it is desired to limit. The movement of the pivoted hammer in one direction is limited by the alternating wing of the adjacent hammer-support and in the opposite direction by the sto y reference to Fig. 1 it will be observed that the stops 13 are arranged in front of the hammers, so that there is no liability of the hammers coming in contact with each other when the machine is at rest or when they are moving at a slow speed. Thus the chances of dulling the hammers or otherwise interfering with them will be avoided. Of course when the speed of the shaft is high the hammers will be maintained in true radial lines from the axis of the shaft or but slightly deflected, owing to contact with the material; but when the machine is slowing down or just started or moving at a slow s eed the hammers might contact with each ot er were it not for the fact that the supports are provided with stops which would limit the forward movement of each hammer.

I have shown what to me at this time appears to be the best construction of the hammer-supports and hammers; but I do not limit myself to the exact form shown, but reserve the right to make such changes and alterations in form, proportion, and minor details of construction as may suggest themselves from time to time and come within the scope of the following claim.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a machine of the class described, the combination with a shaft, of hammer-supports connected to said shaft and each consisting of a plurality of radially-extending wings, said hammer-su ports being so arranged that the wings o one support are arranged midway the wings of the adjacent IOO . tween the outer ends of the wings of alternate si supports, and; continuous rods extending. through the Wings of the supports in front of 5` the' pivots ofthe hammers and adjacent to' said pivots to limit the forward movements of the hammers;substu.ntial1y as described.
